Xiao Bian has always missed the Nokia mobile phones that could hit walnuts in the past, but now the large screen mobile phones do not have such treatment, and the screen may be damaged if you do not pay attention to the ground. There are two channels to replace the mobile phone screen: the manufacturer's after-sales service center and the non manufacturer's after-sales repair shop. The manufacturer's after-sales service center can basically ensure the quality of the replaced screen. The disadvantage is that the maintenance costs are high and the maintenance is not timely; However, the quality of screens used by repair shops not authorized by the manufacturer is uneven, and the cost of accessories varies greatly.
There are three kinds of screens in the mobile phone accessories market: original screen, rear pressing screen and fake screen 。
The quality of the original screen is not fundamentally different from that of the original screen, but the source of the screen is different. The original screens in the market come from the manufacturer's maintenance channels and the external sales of the OEM. Some of them are removed from new or second-hand mobile phones, and the screen price is not different from the manufacturer's supply, but because they are not limited by the manufacturer's after-sales price system, the maintenance cost is cheaper than the after-sales service center.
In the market, there is a kind of screen called post pressing screen, which comes from the screen replaced by the broken external screen of the user's screen. Now smart phones basically use a full fit screen. For example, the screen used by the iPhone 6 has four layers: outer screen glass cover, polarized light, LCD, and backlight. Where is the touch screen? Apple has integrated touch and LCD since the iPhone 5. If only the outer screen glass of the mobile phone is broken and the touch and display are normal, the workshop in the market will separate the outer layer of the broken screen and press the new outer screen glass again. This screen can be reused. This screen with the outer glass cover replaced is the rear pressing screen. The processing cost of the rear pressing screen ranges from 20 yuan to 30 yuan to nearly 100 yuan. The quality and price are quite different from those of the original screen. The outer screen of the original screen is made of Corning gorilla glass, which is extremely hard and scratch resistant; The pressing screen is made of ordinary glass, which is easy to be scratched.
The post processing screen pressing workshop is limited by the materials and production conditions. The post screen pressing workshop generally has the problem of displaying color difference or displaying dark color. There are many reasons for the color difference: the purity of glass used to make the outer screen is not enough, the material problem of the polarizing layer, and the shadowless glue material used to fit the outer screen and the inner screen will cause the color difference of the screen display. The inner After being used for a period of time, the outer adhesive will also change color due to ultraviolet radiation in sunlight and light. Some rear pressure screens may also have dust ingress in the inner and outer layers due to poor dust removal in the processing environment.
Another common problem of the rear pressing screen is that the bracket is easy to fall off. Since the bracket on the original screen needs to be removed when the rear pressing screen is processed to press the outer screen and the liquid crystal, a new bracket needs to be glued on later. The bonding strength between the new bracket and the screen is much weaker than that of the original screen. A slightly longer time or the collision of the outer frame is likely to cause the bracket to fall off, causing the screen to tilt or the screen body to completely separate.
The copycat culture in the past decade has always been accompanied by the mobile phone industry. Some small screen manufacturers also produce compatible mobile phone accessories of big brands. However, the quality control of the screens produced by these small factories is extremely poor, and the raw materials used are poor. Neither the quality nor the display effect can be compared with the original screen or the rear compression screen. The service life of most copycat screens is far less than that of the rear compression screen. The fake screen also has many problems, such as cold and bright screen display color, insufficient screen resolution and graininess.
What kind of screen does the general maintenance shop use?
It has always been the rule of traditional repair shops to leave the store without warranty, Rear pressing screen They are favored by these merchants for their "advantages" of being difficult to distinguish and low in price in a short time. According to statistics, most of the screens replaced in the market use rear pressed screens. What's more, most businesses charge the maintenance price of the original screen.
